Unable to set HAGL_CHAR_BUFFER_SIZE from main

[sisodiakaran]

Hi, I am using the library in ESP-IDF (5.2.1) project. I am willing to use bigger font size so I defined HAGL_CHAR_BUFFER_SIZE in my main file before including hagl.h. But unfortunately it is not being changed to desired size. I am suspecting the scope issue here.
